ICFP 2018 The 23rd ACM SIGPLAN International Conference on Functional Programming https://icfp18.sigplan.org Call for Sponsorships Web version of this call for sponsorships: https://icfp18.sigplan.org/attending/supporting-icfp ## Why Sponsor ICFP 2018? ICFP is the premier conference on functional programming languages, covering all aspects of theory, implementation, and application. Every year, we bring together over 500 world-leading researchers, practitioners, and students to discuss the latest findings, collaborate on new ideas, and meet new people. By sponsoring ICFP, your organization can demonstrate its commitment to supporting high quality research and to developing the next generation of functional programming experts. Most of our sponsorship funds are used to help students from around the world afford to attend the conference and get the most out of their experience. We believe that this commitment will pay dividends for our students, our sponsors, and the public for years to come. If you're interested in becoming a sponsor, we'd love to hear from you: get in touch with our sponsorship team at sponsorship-2...@icfpconference.org ## Sponsorship Opportunities and Benefits ### Bronze - $750 * Your logo on the ICFP 2018 website * Your name listed in the proceedings ### Silver - $3,000 * All of the benefits of Bronze sponsorship * One complimentary 3-day ICFP registration * A table at the industrial reception * Your logo in the proceedings * Your logo on publicity materials such as banners and posters ### Gold - $6,000 * All of the benefits of Silver sponsorship * One additional complimentary 3-day ICFP registration (2 in total) * A named supporter of the industrial reception * An opportunity to include branded merchandise in participants' swag bag ### Platinum - $10,000 * All the benefits of Gold sponsorship * One additional complimentary 3-day ICFP registration (3 in total) * A named supporter of ICFP 2018 * An opportunity to speak to the audience at the industrial reception * A table/booth-like space in the coffee break areas ## Additional Sponsorship Opportunities We offer some additional sponsorship options to sponsors at the silver level or above. ### Lanyard Sponsor - $4,000 You provide the lanyards that every attendee will wear around their neck. ### Video Sponsor - $4,000 ICFP makes videos available for free to non-attendees following the conference.

[racket-users] Racket v6.11
Racket version 6.11 is now available from http://racket-lang.org/ * Typed Racket supports refinement types and dependent function types. Previously an experimental feature, refinement types allow types to describe more interesting properties of values, especially integers. For example, this type shows that the `max` function always produces a number at least as big as its inputs: `(-> [x : Integer] [y : Integer] (Refine [z : Integer] (and (>= z x) (>= z y` * DrRacket's Program Contour is significantly more efficient; using it no longer hurts DrRacket's interactivity. * The `web-server/formlets` library produces formlets that are serializable, facilitating dynamic uses of formlets in stateless #lang web-server servlets. The new `web-server/formlets/stateless` and `web-server/formlets/unsafe` libraries provide additional support with the same API. * The `db` library supports the Cassandra database. The following people contributed to this release: Alex Knauth, Andrew Gwozdziewycz, Andrew Kent, Asumu Takikawa, Ben Greenman, Ben Noordhuis, Carlo Dapor, Daniel Feltey, David Christiansen, David Van Horn, Eric Dobson, Gustavo Massaccesi, Harold Carr, Jack Firth, Jay McCarthy, Jeannie Tran, Jens Axel Søgaard, jgreco, John Clements, Jordan Johnson, Justin Slepak, Leandro Facchinetti, Leif Andersen, Matthew Butterick, Matthew Flatt, Matthias Felleisen, Michael Ballantyne, Milo Turner, Nadeem Abdul Hamid, Philip McGrath, rain, Robby Findler, Royall Spence, Ryan Culpepper, Ryan Davis, Sam Tobin-Hochstadt, Shu-Hung You, Spencer Florence, Stephen Chang, Vincent St-Amour, WarGrey Gyoudmon Ju, and Weng Shiwei.

Re: [racket-users] namespace-variable-value thinks functions are bound to syntax
Yes, because keyword functions expand to macro definitions that try to optimize keyword applications. namespace-require and namespace-variable-value are relatively low-level operations on modules and namespaces. Using dynamic-require could be a bit easier: #lang racket (module p racket (provide (all-defined-out)) (define (foo0 a b) (+ a b)) (define (foo1 a b [c 3]) (+ a b c)) (define (foo2 a b [c 3] #:kw1 kw1) (+ a b c)) (define (foo3 a b [c 3] #:kw1 kw1 #:kw2 [kw2 1]) (+ a b c)) ) (require syntax/location) (define ns (make-base-empty-namespace)) (parameterize ([current-namespace ns]) (dynamic-require (quote-module-path p) 'foo0)) ;=> # (parameterize ([current-namespace ns]) (dynamic-require (quote-module-path p) 'foo1)) ;=> # (parameterize ([current-namespace ns]) (dynamic-require (quote-module-path p) 'foo2)) ;=> # (parameterize ([current-namespace ns]) (dynamic-require (quote-module-path p) 'foo3)) ;=> # Please note that dynamic-require handles macro exports specially, as stated in the doc: https://docs.racket-lang.org/reference/Module_Names_and_Loading.html#%28def._%28%28quote._~23~25kernel%29._dynamic-require%29%29 > If the module exports _provided_ as syntax, > then a use of the binding is expanded and > evaluated in a fresh namespace to which > the module is attached, which means that > the module is visited in the fresh namespace. > The expanded syntax must return a single value.

Thanks Stephen for giving our wiki some much-needed love!

Good style proposes to use provide like this: #lang racket ;; ‘server’ module (provide ;; Number -> Number ;; the identify function on numbers identity ;; Number -> Zero ;; the 0 function on numbers zero) ;; - - - ;; implementation (define (identity x) (local-identity x)) (define (zero x) 0) ;; Number -> Number ;; does some random stuff (define *return #f) (define (local-identity x) (call/cc (lambda (return) (set! *return return) (*return (+ (- x 1) 1) #lang racket ;; client 1 (require “server.rkt”) ;; now you see both identify and zero #lang racket ;; client 2 (require (only-in “server.rkt” zero)) ;; now you see only zero etc. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Vous obtiendrez de meilleures réponses en anglais pour cette liste, mais je vais essayer avec l'aide de google translate. nécessitent des modules pulls dans votre script, fournissent les rend disponibles pour être requis. Les détails sur require sont ici: https://docs.racket-lang.org/reference/require.html Exemples: hi_bye.rkt #lang racket (provide (all-defined-out)) ; tout ce qui est défini sera disponible pour d'autres scripts (define (say-hi) (displayln "hi!"))
